ANTIOCH – Deputies from the McHenry County and Lake County sheriff’s offices were involved in a shooting that killed a man early Saturday morning in Antioch, an official said.

The man, 53-year-old Gerald Robert Boyes, brandished a handgun when officers were attempting to take him into custody, Assistant Commander of the Lake County Major Crime Task Force Thomas Nugent said. Officers shot Boyes, and he was pronounced dead at the scene, Nugent said.

Boyes’ last known address was in Jacksonville, Florida, Nugent said.

Police in western Kentucky named Boyes as a person of interest in the Tuesday slayings of Boyes' parents, 67-year-old Billie Potter and 73-year-old Gerald Boyes.

McCracken County (Kentucky) Sheriff Jon Hayden said in a statement that a stolen car linked to Boyes was seen at the Illinois pizzeria. Hayden says Boyes was shot after brandishing a handgun in front of officers.

Boyes was wanted for a probation violation from the state of Florida, Nugent said, and possessed a vehicle that was reported stolen from Florida.
